Sega Hacking Projects

Weaken the B-check - 3 steps done One-Timers Less Accurate One-Timers Only! Intro / What is this? In short, with my guidance you do some of the lead-up work for hacks, using emulator tools to find the basics of where/how to make hacks, then I'll finish off any coding needed for the hack. This begins a series of hack posts where I lay out how to help me with the early parts of discovering how to do a hack. This series should train up a few guys to be great at investigating the starting stages of hacks to give me the info needed to complete the hack -- or to discover that the hack may not be possible. Often these steps can be done in 5-30 minu…

Hi everyone! I (with lots of help from ai tools) have made a HTML app that runs locally and that basically works as a season mode for NHL94. So it's pretty tech neutral and will run in any browser. The game schedule is the exact same as the real season 1993-94, the rosters are based on the Genesis rosters. You just pick a team and start the season, you play the game "for real" on your system and then report it into the app in your browser (goals, assists and penalties). You can also simulate the game. There's a save and export file function as well. I really hope it works. I've tested it a lot and I think that the results and player stats shou…

I have been working on a smaller goal mod for NHL 94 on Genesis. I have edited the artwork to work with the code that edits the barrier of the goal posts and of the boards. So this is complete with accurate collision of the goal posts with the puck with updated goal artwork. There are several different sizes of goals. Here are some photos of the smallest goal: (updated 11/16/19) Playing roms with this goal size produces very low scoring games. One way I have made this goal size more playable is by lowering goalie glove ratings to create more shots that bounce off the goalie. Smallest Goal v1.1 ROM : (released 12/28/19) smallestgoalFBFF0000v11…

I wanted to do a proof of concept to show that we should be able to mod NHL 94 to use the Sega CD music via an MSU-MD patch. This would make it compatible with specific emulators (such as Retroarch+GenesisPlusGX), real hardware (cartridge+cd) and also flashcarts that have Sega CD support (like the Everdrive Pro). I was able to put this together today using the NHL 92 source code as a base for convenience since its fully disassembled at this point (thats not to say this can't be done in 94 today-- I think we have enough knowledge on the 94 source to do it) How was it done? 1. Set up file structure to use within Retroarch+GenesisPlusGX. NHL92…

I know this has been discussed in other topics but the problem persists and I think it's important to have a topic about this so that something can be done about it. The issue is multi-layered, it's primarily how's how fast the goalies are, how even if you lower a goalie's speed to the lowest value, they don't slow down very much, and this affects how easily Goalies can knock down skaters. The main issue that I'm trying to address is the all too common breakaway-skate-into-goalie-fall-down before getting the shot off sequence. Or when a Goalie chases the puck behind the net and as a skater you are trying to get to the puck but the goalie is there, you know if you run…

Hello: I was looking at this website and I wanted to ask you if there is anyway to have the speed of the game edited? I like the stock fastest speed with the precise passing involved and I don't like it when the stock game slows down the and it just drags out and the players are skating real slow and aren't going after the puck etc.., but when you have a fast game with someone or against the computer and it's fast throughout the whole game, it's great. You can have some really great games. There are a lot of different things I'd like to edit but the first is the speed? Or are there any Roms already created that change this option please? …

I'm making this thread to help me focus this project-- I find writing things down like this brings me some clarity for my direction. As you may or may not know, the PC version of NHL 94 (aka NHL Hockey) and NHL 95 uses sprites with many more color zones, which allow for much more accurate jerseys. Comparison: Not only is the jersey striping more accurate, but it even includes the crest. The reason this is possible, is while the Sega Genesis supports only 64 colors (of which 16 colors are dedicated to the home team, and 16 colors are dedicated to the away team; one color has to be dedicated to transparency, so its actually really 15 colors), the P…

i hope this is the right place for this thread ☺️ so i managed to finally get hakchi to work. thank god for my laptop! i began with uninstalling an outdated avira antivirus on my laptop, disabled both windows firewall and antivirus and i also found some included vpn on my windows there, it didnt look active but i unckecked the 2 alternatives it had just to be sure it was really not active. then i downloaded and ran hkachi(version 3.7 because thats the one they use in all guides), plugged in my sega according to the instruction and after some minutes i got the install success icon and the green icon instead of the red one 😀 i first tried this on my normal p…

NHL '94: Wide Display Mode (“widescreen”) Hack v2.0 Status: Stuck at ~93% ~94% ~95% ~96% ~99% 100? updated 2025 07 26 To anyone reading this thread, please note that the content has been superseded by a v3.x hack. Check it out at the link below! The content below this point is now outdated, and will not be updated. The existing Wide Display Mode patches change the game to use the 320 pixel wide video mode instead of the 256 pixel wide video mode in most gameplay screens. This causes many cosmetic bugs, and I've been on a quest to try to fix every single last issue myself, for both the original and 32-team ROMS. Alas, I could't quite get it to 100…

For convenience, you can simply download the zip file and run the included build.bat file. Technical Info For those interested, below is some more detailed info on what was needed to get the code compiling. The original compiler used to build the source code was…

I just discovered that ROMHacking.net has wiki-like pages that we can use for sharing our discoveries of the ROM and RAM data (for example, where to find the scores in the RAM, or where the songs are in the ROM). NHL94 Sega: https://www.romhacking.net/games/2092/ Example (Sonic): ROM RAM I'll start copying some of my notes into these...

Intro / What is this? In short, someone (or someones) please do the relatively easy Steps 1, 2, 3, and 4 of this hack for me, based on my instructions below. This begins a series of hack posts where I lay out how to help me with the early parts of discovering how to do a hack. This series should train up a few guys to be great at investigating the starting stages of hacks to give me the info needed to complete the hack -- or to discover that the hack may not be possible. Often these steps can be done in 5-30 minutes. So I hope people will follow the instructions in these HelpMeHack threads in order to find for me the early parts of hacks. And then these people will …

I have been thinking about this for a while and decided I should at least start this hack and post on the forums for documentation/progress. My initial thought process is as follows: I assume the blood animation is a separate graphic and not an entirely new set of sprites (CONFIRMED) Find the blood animation tiles in NHLPA'93 (DONE, most likely) Trace and reverse engineer the code on a blood injury in '93 (current phase) Bring those elements into '94 I think the first two bullets I will confirm and get done rather quickly, but the hard work will be understanding and isolating the code in '93. My starting assumption will be that when an in…

I managed to find out how to adjust the speed of the game clock in NHL '94 on Genesis. Attached is an original NHL '94 genesis bin file. (unedited except for the clock speed / penalty minutes hex adjustments) Please test this out and provide me your reviews if you like it. It may take some getting used to the longer periods in NHL '94, but I'm hoping that you find this useful. I am trying to learn how to make other aspects of the game more realistic to make the game more playable when using a slower game clock speed. Here is the hex address to adjust the speed of the clock : 015DEC:0AAA ; 0AAA is the original value, I lowered it to 03AA which slows dow…

I discovered a code that turns the Auto Player Switching Off in NHL 94 on Genesis. With this code enabled, when a teammate gains control of the puck, you no longer are switched to the player with the puck. You remain in control of the player you were controlling while the CPU controls the player with the puck. (If you press the B button, you will then switch to the player who has the puck) This code allows you to control players who don't have the puck and lets you stay in control of a single player for as long as you want. (Until there's a face-off, where control resets back to the Center) It's been determined that the best way to enable this code is to edit the rom…

Concept you should be familiar with ahead of time: * Hex values and a Hex Editor * Tile Molester * Basic Graphics (Tiles, palettes) There is an issue in NHL Hockey (sometimes referred here as "NHL'92") where the away team's sprite in the penalty box shows the home team colors on their socks. Essentially, there are two tiles that are using the home team palette but should be using the away team palette. The goal was to find out where this information was in the ROM and change it from home palette to away palette. The following is the process I used, in case this helps out others in the future. The first step I did was to find the actual tiles in…

To Genesis Sports Enthusiasts!!! I'm aware that NHL94' website is mainly for the NHL series, but with the recent news that Tecmobowl.org is no more (RIP). This is one of the last places people, gamers, modders, and anyone for a debate can go and tickle that itch. This post / project is to get some help on some of the games that are long over do for a refresh/overhaul. Triple Play Baseball (I've managed to get it cleaned, and rosters updated, especially without the dreaded "Ghetto City" or Jim's, or Frank's TEAM.) World Series Baseball (I've updated all the rosters (attributes as well), found the logos. But needing help on main screen, and some other…

Hello, So long, NHL94 forum. I am currently working in another project for brazilian retro gamers which is MSU-MD Futebol 1.0 (I am thinking about to change for another title). I have a full excel with relevant information about hacking FIFA Soccer 95 that I completed since 2018 I have seen there is almost nothing pending to find out in NHL94 Sega Genesis Rom. That's my goal for FIFA Soccer 95. I am going to need help finding the following: 1) FIFA Soccer 95 Menu Background. I don't have a clue where to find. As far as I am concerned, this type of menu is based on 4 screens, giving the effect the menu is "flying" in front of the background. This must be compres…

Hello Fellow Members, Ive been doing some digging into future roms, and have located the Team Offsets from NHL96, 97 and 98. Im not sure if these have been found already, but thought to share my findings. Tested the values and found each version of NHl from 93-98 had the players data in HEX editor starting 104 bytes after team-offset. However, 96-98 were all the same and were only a 100 bytes away. NHL 93 - Team-offset to extract rosters - 314 (thanks to @smozoma in his original post NHL 94 - Team-offset to extract rosters - 30E (thanks to @SabreFan1) NHL 95 - Team-offset to extract rosters - 772 (thanks to @kingraph) NHL 96 - Team-offse…

Hi all, I started the last year a hack of FIFA Soccer 95, that I'm calling FIFA Soccer 2020 because I am updating to 2019-2020 season. The first idea was just an update of players, teams, first and second kits, etc. After long time working and analyzing the rom I had more interest in doing something more serious, so I went further, such as insert new audios to the game, music, add new graphics, design banners, add a new intro or header to the game. I can say I am in an intermediate level. After this introduction I am going to explain what I would like to correct. I did a new intro for the game. Instead of showing the classical EA Sports screen, an audio saying…

@UltraMagnus is currently putting together a '94 ROM for the EIHL (British league), because he is an absolute legend. I have sorted the team and player details, along with the kits, and have nicked @MonkeyHead's ratings from a '95 ROM for the same league. It seems to be coming along quite nicely. The ROM is based on the rosters at the end of the 2019/20 season, which featured (as normal) 10 teams. Due to Covid, a full 20/21 season is not going ahead as normal, but... a massively shortened season / glorified tournament is going ahead with 4(!) teams only. When the '94 ROM is completed, there will be 10 teams. Let's call them teams (1) to (10). In the ROM, th…

Evening all @UltraMagnus has just finished an awesome EIHL version of '94, which I have been putting through its paces this evening. The EIHL only features 10 teams, so I was wondering whether there is a way to amend the in-game play-off bracket screen so that it only shows the 10 teams in the league, rather than the hidden NHL teams. The ROM has already been tweaked in EARE so that only the 10 EIHL teams are selectable for a play-off run. I know you can change the brackets in NOSE but I couldn't see anything that allows you to actually delete teams from the brackets. Ignore the names here, as we have padded the ROM with other British teams so that t…

Hello All, I'm doing something that might have been attempted or not. But thought the conversation may need to be asked. What are your thoughts of merging NHL94 and NHL95? Using the players from 94 in 95? Using end of period/penalties screen from 94 into 95?

Hi all, I am currently working on my latest project "UEFA Champions League 2021", a hack from J-League Pro Striker 2. As many of you know, the original game was released only in Japan, so almost the full game is in Japanese. I am having a hard time adapting some screens from original Japanese Kanji to Spanish because of the limitation of characters. But this is not the big issue. The main problem that's happening in a couple of screens (maybe three or four), is the "forced" tile orders or tile patterns those Kanji have. I understand that because it is pointless to repeat the same tile on and on and it is a good idea to save ROM space. Below an example: …

A few days ago I started a project of hacking NBA Live 97 from Sega Genesis. I will convert it into FIBA World Cup (no year) with up-to-date rosters based on the event and performances of the 2019 FIBA World Cup in China . What I have done until now is modify the names of the teams, insert a few logos and modify three rosters (for Spain, Argentina and Brazil). It is a project I am working slowly and I want it finished before summertime. I have to recognise I don't watch too much basketball since 2009. So, what I need for this project is someone who was an expertise on international basketball: Must know most of the players. Players main attributes. Players Str…
